Marking episode first/last showings performance
Mythfilldatabase's "Marking episode first showings" and "Marking
episode last showings" steps take a combined 21+ minutes on my backend
server. After attempting MySQL and filesystem tuning with no success,
I cut the updates down to 5 seconds by modifying mythfilldatabase's
queries to update in bulk rather than row-by-row.
Besides the performance improvement, the "Found" number is changed to
the actual number of programs marked instead of the number of unique
programs. The number marked is higher than the unique count because of
duplicate channels (non-HD and HD variants, Comcast in the middle of a
massive renumbering).
Fixes #10482
